Disclosed are an electric vehicle capable of improving the charging efficiency of a charging apparatus by reducing the switching loss that may occur in the charging apparatus of an electric vehicle and a charging apparatus thereof. To this end, a power factor correction apparatus of an on board charger includes a first boost circuit receiving AC power through a first inductor to charge a load, a second boost circuit receiving the AC power through a second inductor to charge the load, and a third inductor provided between a leg of the first boost circuit and a leg of the second boost circuit so that parasitic capacitors of the first boost circuit and the second boost circuit are discharged.

Electric vehicle and charging apparatus thereof

The present invention relates to an electronic device and a method for controlling a charging operation of a battery. The charging control method includes charging a battery using a first charging mode, if a current voltage of the charged battery coincides with a predetermined voltage, decreasing an intensity level of a charging current and charging the battery using the decreased charging current intensity, and if the decreased charging current intensity coincides with a predetermined current intensity, converting from the first charging mode to a second charging mode and charging the battery using the second charging mode.
